You would have to pull the trigger nine times on a pistol to put the same kind of stopping power into an assailant as a single shotgun shell. (…)
Shotgun recoil can be tamed in a variety of ways. For example, consider using a 20 gauge instead of 12 gauge shotgun. [ed’s note: My bay-bee! Sometimes I just like to look over and watch it sleeping…]
A 20 gauge shotgun loaded with #3 buck (20 .25 caliber pellets) is nearly as effective on human targets in across-the-room distances as a 12 gauge loaded with 00-buck, but has significantly less recoil. (…)
If someone comes into your home to do you harm, racking the shotgun will not scare them away. Through rage, socialization or drugs human predators are frequently incapable of feeling fear or compassion. Making noise will not likely stop an attacker. Lead will.
Note to self:
Federal Power-Shok 20 Gauge, #3 Buck – Full power, yet easier shooting that 12 gauge, these shells load 20 #3 buck pellets and launches them at 1200 fps. The tight patterns mean a devastating impact on any unwanted house guests. Expect to pay around $4.50 for a box of five.
